Control Data Functions
1.P0 P2:Segment / PWM / General Purpose output port switching control data
These control bits are used to select the function of the S1/P1 to S6/P6 output pins (Segment Output Pins or PWM Output
Pins or General Purpose Output Pins).
Please refer to the table below.

PWM output or General Purpose output is selected by PGx(x=1 6) control data bit.
When the General Purpose Output Port Function is selected, the correspondence between the output pins and the
respective display data is given in the table below.

When the General Purpose Output Port Function is selected, the respective output pin is output a “HIGH” level when it
corresponding display data is set to “1”. Likewise, it will output a “LOW” level, if its corresponding display data is set to
“0”.
For example, S4/P4/G4 is used as a General Purpose Output Port, if its corresponding display data – D13 is set to “1”,
then S4/P4/G4 will output “HIGH” level. Likewise, if D13 is set to “0”, then S4/P4/G4 will output “LOW” level.
2. DR: 1/3-Bias drive or 1/2-Bias drive switching control data
This control data bit selects either 1/3-Bias drive or 1/2-Bias drive.

3. DT: 1/4-Duty drive or 1/3-Duty drive switching control data
This control data bit selects either 1/4-Duty drive or 1/3-Duty drive.
